Hi there, Thanks for your query. * Firstly, Stomach cancer at this age is rare. Taking an Endoscopic biopsy does not mean it is cancer. * Secondly, Prolonged nausea is most commonly due - to chronic acidity (particularly as a result of a infection/inflammation by a bacteria called H.pylori.). H.pylori infection is usually diagnosed through biopsy of inner lining of the stomach/duodenum. A 10-14days course of anti-H.pylori therapy eradicates the infection. - Chronic indigestion due to harmful bacteria overwhelming the good bacteria in the intestine. A course of Probiotics, such as, lactobacilli, along with digestive enzymes overcome this problem. - Chronic Protozoal infection (amoebae, giardia) which can be easily treated with a course of metronidazole group of drugs. - Worms in the intestine :- a deworming course eliminates worms. - A sluggish intestine, whereby which the movement of food through the stomach and across the intestine is slower than normal. Prokinetic agents relieve the condition. If I were your treating doctor, I would have - pending your appointment with GI doctor- prescribed Probiotics, Pro-kinetics, deworming course and, of course, anti-H.pylori therapy along with anti-acids + anti-nausea drug, such as, ondansetron. You may discuss my views/opinion/recommendations with your GI doctor, who would know what is best for you. Hope I have answered your query. Dr. Rakesh Karanwal
